Why is Termux Emacs loading so many packages? #4739

Closed makoto-yamashita closed 4 years ago

makoto-yamashita commented 4 years ago

Termux Emacs is very slow due to the load of many packages. When emacs --daemon -Q is executed, 100 packages are loaded. In particular, loading all the languages are very slow. (chinese, cyrillic, indian, sinhara, english, ethiopic, european, czech, slovak, romanian, greek , hebrew, japanese, korean, lao, tai-viet, thai, tibetan, vietnamese, georgian, khmer, burmese, cham)

How can we skip these files?

The reason you are seeing these packages being loaded is because our emacs is not dumped. You can play around with disabling packages by editing $PREFIX/share/emacs/26.3/lisp/loadup.el.

Note that it is possible to dump emacs with the new portable dumper, but I haven't figured out how to cross-compile a dumped emacs (see https://github.com/termux/termux-packages/pull/4622). It is possible to compile emacs on device though and get a fast-starting, dumped, emacs.
